ATMworks 950L Adapter

This document provides a comprehensive guide for installing and configuring the Digital Equipment Corporation ATMworks 950L network interface card (NIC) and its associated Aruba 3.2 software on UNIX-based Sun Workstations (Solaris and SunOS).

The guide covers:

1. Hardware Installation: Detailed steps for physically installing the ATMworks 950L card into an SBus slot, including system shutdown procedures, unpacking, inspection, and proper attachment of Multimode Fiber (MMF) or Category 5 (CAT5) cables. Technical specifications for both MMF and CAT5 versions are also provided.
2. Software Installation: Instructions for installing the necessary drivers, diagnostics, and management software from 8mm tape or CD, outlining system requirements and specific pkgadd (Solaris) or tar/install_pkg (SunOS) commands. Procedures for removing software and reconfiguring the card after moving it to a new slot are also included.
3. Hardware Diagnostics: How to use the decdiag utility to perform self-tests and verify the functionality of the ATMworks 950L card and its drivers.
4. System Configuration: A major section detailing how to configure the ATMworks 950L for ATM network communication using the decconfig utility. This includes:
   • Setting up Interim LAN Management Interface (ILMI) and signaling for Switched Virtual Connections (SVCs).
   • Configuring LAN Emulation (LANE) Clients (LECs), including IP addresses, Peak Cell Rates (PCRs), inactivity timeouts, MAC addresses, and ELAN names.
   • Implementing Classical IP (CIP) over ATM, which involves assigning IP addresses, setting up an ATM ARP server, and defining Permanent Virtual Connections (PVCs) with specific Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) numbers and transmission rates.
   • Managing DCM access security.
5. Troubleshooting: Answers to commonly asked questions and solutions for various issues encountered during or after installation, such as system boot failures, driver loading errors, and network connectivity problems.
6. Advanced Information: A "Hacker's Guide to decconfig" lists configuration files, and an appendix addresses specific considerations for configuring ATM-only networks, including issues with NIS/NFS support.
